Epson I+ - Manual (Page 24)

Switch 1 (keyboard)-tells your computer what kind of keyboard is attached
to your system. The factory setting is off for the standard (enhanced) key
board which comes with your Equity I+.
Switch 2 (coprocessor)-tells your computer whether or not an optional math
coprocessor is installed. The factory setting is on to tell the system that this
option has not been installed.
Switches 3 and 4 (memory size)-indicate how much built-in memory is avail-
able. These switches should never be changed unless you install a memory
card and you want to use part of the optional memory instead of the built-in
main memory.
The system always checks the amount of available memory each time it is
reset. Problems may occur if the switch settings do not agree with the
amount of main memory in use.
Switches 5 and 6 (monitor type)--define what type of video card and monitor
you are using and help the system address the adapter memory correctly. Set
these switches as follows:
l
If you have a monochrome monitor and video card, set both switches
Off.
l
If you have an enhanced graphics adapter set both switches on, no mat-
ter what type of monitor you have.
l
If you have a color graphics adapter and an RGB monitor, set switch 5
on and switch 6 off.
l
If you are using a composite video monitor, and its resolution is poor,
you may want to set switch 5 off and switch 6 on. This selects 40-column
text mode for your screen and improves the resolution.
Switches 7 and 8 (floppy disk drive&indicate how many floppy disk drives
your system has. These switches are very important and should be set as
follows:
l
If you have a single drive, set both switches on so the operating system
knows that it must provide help when disk B: is required.
l
If you have two floppy disk drives, set switch 7 off and switch 8 on so the
lower drive is not ignored.
l
If you add external floppy disk drives, for a system total of four, set
switches 7 and 8 as indicated in Table 1-2.
